TECHNICAL FIELD

Exemplary embodiments relate generally to systems and methods forcontrolling operations of a display unit based on, at least in part,orientation of the display unit.

BACKGROUND AND SUMMARY OF THE INVENTION

Electronic displays have grown in popularity not only for indoor use,but also for outdoor use. One exemplary application, without limitation,is the digital out of home advertising market where the electronicdisplays are increasingly replacing the use of static posters. The useof electronic displays is advantageous because such electronic displayspermit images to be changed quickly as well as permit the use of videosand interactive displays, among other benefits.

Such outdoor electronic displays experience solar loading. Such solarloading may result in significant heat loads to the electronic displayand related components which may result in damage if not thermallymanaged properly. However, such thermal management efforts require theconsumption of additional power. Ambient solar conditions also affectimage quality. Electronic display brightness sometimes needs adjusted tomake an image visible. The direction an electronic display is facing mayaffect the amount of solar loading or other exposure received by theelectronic display, and thus affect the need to provide thermalmanagement and/or brightness levels, for example. What is needed is adisplay unit which controls operations based on, at least in part,orientation of the display unit.

A display unit which controls operations based on, at least in part,orientation of the display unit is provided. The display unit maycomprise a housing for one or more electronic displays. Such electronicdisplays, and other components of the display unit, may be cooled orotherwise thermally managed using fans, open loops for ambient air,and/or closed loops for circulating gas, for example. The display unitmay comprise a controller. The controller may comprise one or more of:an orientation detection device, an accelerometer, a timekeeping device,a location tracking device, a database, and a sensor. The orientationdetection device may comprise a magnetometer, though any type oforientation detection device is contemplated. The aforementionedcomponents may be in electronic communication with a processor, whichmay be local to or remote from such components. The processor mayreceive readings from such components. From such readings, one or moreof: the tilt angle of the unit, the location of the unit, the time ofday, and/or the display unit's direction or other orientation may bedetermined. From such information, the solar angle relative to eachelectronic display may be determined. The display unit's operations maybe adjusted based upon the solar angle. For example, without limitation,a number of predetermined ranges may be provided and the electronicdisplay's brightness and/or speed of the cooling fans may be adjusted topredetermined criteria for each such range.

As another example, without limitation, such information (e.g., the tiltangle of the unit, the location of the unit, the time of day, and/or thedisplay unit's direction or other orientation) may be used to determinewhether or not a display unit is installed properly. For example,without limitation, such information may be used to determineapproximate deviation from plumb.

Examples of other such sensors include vibration and/or shock sensors.Data from any of the orientation detection device, the accelerometer,the location tracking device, the vibration sensor, the shock sensor,combinations thereof, or the like may be used to detect damage to thedisplay unit. Such damage may be, for example, without limitation, as aresult of vandalism, vehicle collision, natural disaster, or the like.Where such possible damage is detected, such as by exceedance of animpact/shock level, the tilt angle and/or orientation may be determinedand compared to expected measure to confirm such damage. Alerts may beprovided where such possible damage is detected.

As another example, without limitation, such information (e.g., the tiltangle of the unit, the location of the unit, the time of day, and/or thedisplay unit's direction or other orientation) may be used to determinewhether or not a door or other access panel of the unit is opened orclosed, assuming the sensor is mounted on or otherwise connected to thedoor or access panel.

Communication betweenany such components of the display unit 10 or remote therefrom may beaccomplished by wired and/or wireless connection.

FIG. 3 is a flow chart with exemplary logic for use with the controller20. The tilt angle of the display unit 10 may be determined. Inexemplary embodiments, the tilt angle may be determined from datareceived from the one or more inclinometers 26. Alternatively, oradditionally, the tilt angle may be determined by the orientationdetection device 22. The location of the display unit 10 may bedetermined. In exemplary embodiments, the location may be determinedfrom data received from the one or more location devices 28, though thelocation may alternatively, or additionally, be pre-programmed. The timeof day may be determined. In exemplary embodiments, the time of and/ordate may be determined from data received from the one or moretimekeeping devices 24. The direction the display unit 10 is facing maybe determined. In exemplary embodiments, the direction the display unit10 is facing may be determined from data received from the one or moreorientation detection devices 22.

The solar position may be determined. The solar position may be measuredby the solar angle. The solar angle may be determined relative to thedisplay unit 10, a particular one of the one or more electronic displays14, and/or each of the one or more electronic displays 14. The solarangle may be determined relative to other components of the display unit10. The solar angle may be determined, in exemplary embodiments, byretrieving the solar data from the database 32 indicating the positionof the sun for the location, the time of day, and/or the date.Additionally, the tilt angle of the display unit 10 may be used todetermine the solar angle relative to the surface of each of the one ormore electronic displays 14. By way of a non-limiting example, where thesun is located at 45 degrees relative to the horizon, and the displayunit 10 and/or the electronic display 14 is located at 5 degrees upwardangle relative to the horizon, the solar angle may be determined to be40 degrees. Additionally, or alternatively, the direction of the displayunit 10 may be used to determine the solar angle relative to the surfaceof each of the one or more electronic displays 14. By way of anon-limiting example, where back-to-back electronic displays 14 areutilized, the solar angle for a first one of electronic displays 14,which faces the sun, may be 20 degrees, while the solar angle for asecond one of the electronic displays 14 may be zero and/or a negative,which faces away from the sun.

The determination of the solar angle may be used to adjust operations ofthe display unit 10. For example, without limitation, where the solarangle is likely to result in greater sun exposure and/or solar loading,the controller 20 may be configured to increase fan speed, increasebrightness of the electronic displays 14, some combination thereof, orthe like. This may improve cooling and/or image quality. Where, forexample, without limitation, the solar angle is likely to result inreduced sun exposure and/or solar loading, the controller 20 may beconfigured to decrease fan speed, decrease brightness of the electronicdisplay 14, some combination thereof, or the like. This may decreasepower consumption.

Such determinations and alternations to display operations may be donebased solely on solar angle or in conjunction with other data measuressuch as, but not limited to, ambient weather conditions, ambientlighting conditions, combinations thereof, or the like. For example,without limitation, weights may be applied to each factor and/or certainfactors may be prioritized.

The solar angle may be measured relative to the horizon, a particularcardinal direction (e.g., north, south, east, or west), zenith, somecombination thereof, or the like. The solar angle calculated maycomprise the attitude, elevation, azimuth, zenith, some combinationthereof, or the like. Solar angle may be measured using known or yet tobe developed techniques.

Feedback may be received and operations of the display unit 10 may befurther adjusted as needed. For example, without limitation, temperaturereadings may be taken from the thermal management components 34 toensure temperatures are within predetermined ranges and fan speed may beincreased or decreased accordingly. As another example, withoutlimitation, illumination readings of illumination elements for theelectronic displays 14 may be taken from the thermal managementcomponents 34 to ensure the electronic displays 14 are illuminatedproperly and illumination may be increased or decreased to meetpredetermined criteria.

FIG. 4 illustrates other exemplary logic for the controller 20. Displayunit 10 tilt readings from the inclinometer(s) 26 and/or orientationreadings from the orientation detection device(s) 22 may be used todetermine whether or not a display unit is installed properly. Forexample, without limitation, such information may be used to determineapproximate deviation of the display unit 10 or components thereof fromplumb or other predetermined design measure.

Data from the orientation detection device 22, the inclinometer(s) 26,and/or the other sensors 40 may be used to detect damage to the displayunit 10. Such damage may be, for example, without limitation, as aresult of vandalism, vehicle collision, natural disaster, or the like.For example, without limitation, certain readings from the other sensors40, such as, but not limited to, shock and/or vibration sensors, mayindicate damage to the unit 10. Following detection of such possibledamage and/or as part of routine assessment, data from the orientationdetection device 22 may be used to remotely confirm and/or assess theextent of such possible damage. In exemplary embodiments, where readingsfrom the other sensors 40 indicate damage to the unit 10, data from theorientation detection device 22 may be automatically retrieved toconfirm and/or assess the extent of such possible damage. For example,without limitation, if the tilt angle and/or orientation deviates froman expected parameter by more than a threshold, the existence of damagemay be considered confirmed. The expected parameter may be a designparameter, last reading, a predetermined threshold, combinationsthereof, or the like. If a finding of damage is confirmed, an electronicnotification and/or data regarding the same may be sent to one or moreremote devices.

FIG. 5 illustrates other exemplary logic for the controller 20. Some orall of the orientation detection device 22 may be positioned on aparticular part of the display assembly 10 to determine the position ofthe particular part of the display assembly 10 relative to a remainingor other portion of the display assembly 10. For example, withoutlimitation, some or all of the orientation detection device(s) 22 may beplaced in one or more access panels (e.g., door), side assemblies, orother framework comprising the electronic display 14, combinationsthereof or the like, and may be used to determine whether or not suchportion of the display unit 10 is in an opened or closed position. Forexample, such portions may be movable relative to a frame, the housing12, installation mount, or other structure which may be, directly orindirectly, installed at or otherwise connected to a ground surface,sidewalk, building, wall, vehicle roof, combinations thereof, or thelike. In this way, the opened or closed nature of such portions may bedetermined relative to such a frame, housing 12, installation mount, orother structure. In exemplary embodiments, angles or orientations beyonda predetermined threshold (e.g., 10 degrees) may indicate the portion inan opened position. The predetermined threshold may be set relative to afixed point (e.g., horizontal or vertical), or to an expected threshold(e.g., 0 degrees, 45 degrees, 90 degrees, etc.).

The display unit 10 may comprise one or more network connection devices.The network connection devices may facilitate connection to one or moreintranets, internets, cellular networks, the world wide web,combinations thereof, or the like. With the location and/or timeinformation from the location tracking device and/or the time keepingdevice as well as network connectivity, the display unit 10 may beconfigured to retrieve a number or various datapoints. Such datapointsmay be received at the controller 20 and may be utilized to alterdisplay operations. For example, without limitation, such datapoints mayinclude near real time environmental conditions (e.g., relativehumidity, wind speed/direction, barometric pressure, temperature,precipitation, cloud cover, solar intensity, UV index, sunset/sunrisetimes, combinations thereof, or the like). The controller 20 may usesuch data, by itself and/or in combination with the solar angleinformation, to control one or more thermal management components 34,such as, but not limited to, the fans, illumination devices,combinations thereof, or the like.
